2. Synthesis of Hormones: It aids in the production of steroid hormones like cortisol in the adrenal glands, which help the body respond to stress.
3. Formation of Red Blood Cells: Pantothenic acid supports the formation of red blood cells, which are crucial for delivering oxygen throughout the body.
4. Synthesis of Cholesterol: It plays a role in the synthesis of cholesterol, which is important for building cell membranes and producing certain hormones.
5. Wound Healing: Some studies suggest that vitamin B5 may help speed up wound healing and reduce scarring.

Sources of Vitamin B5

Vitamin B5 is found in a wide variety of foods. Some rich sources include:

• Meat: Chicken, turkey, beef, liver, and fish
• Dairy: Milk, yogurt, cheese
• Eggs
• Vegetables: Broccoli, sweet potatoes, avocados, mushrooms
• Whole grains: Whole wheat, brown rice, oats
• Legumes: Lentils, chickpeas, and peas

Daily Recommended Intake

The recommended dietary allowance (RDA) for vitamin B5 varies by age and gender:

• Adults: 5 mg/day
• Pregnant women: 6 mg/day
• Breastfeeding women: 7 mg/day

Deficiency and Symptoms

Although vitamin B5 deficiency is rare because it is found in many foods, it can occur in cases of severe malnutrition. Symptoms of deficiency can include:

• Fatigue
• Irritability
• Numbness or burning sensation in the hands or feet (paresthesia)
• Digestive issues

Glycogen is a complex, branched polysaccharide made up of glucose molecules. It serves as the primary storage form of glucose in animals and humans, particularly in the liver and muscles. Glycogen plays a crucial role in maintaining energy balance in the body by acting as a readily accessible energy reserve.

Key Points About Glycogen:

1. Structure: Glycogen is a large, branched polymer of glucose. It consists of glucose units linked mainly by α-1,4-glycosidic bonds, with branches formed by α-1,6-glycosidic bonds at intervals.
2. Storage:

• Liver: Glycogen stored in the liver helps maintain blood glucose levels, especially between meals or during fasting. The liver can break down glycogen into glucose and release it into the bloodstream when needed (a process called glycogenolysis).
• Muscles: Muscle glycogen is primarily used to fuel muscle activity during exercise. Unlike liver glycogen, muscle glycogen is not directly released into the bloodstream but is used locally by the muscle cells for energy.

1. Function:

• Energy Reserve: Glycogen is a quick source of glucose, which can be broken down to provide energy (in the form of ATP) during periods of high energy demand, such as exercise or fasting.
• Regulation: Glycogen synthesis (glycogenesis) and breakdown (glycogenolysis) are tightly regulated by hormones like insulin, glucagon, and adrenaline. Insulin promotes glycogen storage, while glucagon and adrenaline trigger its breakdown.

1. Role in Metabolic Disorders: Abnormalities in glycogen metabolism can lead to medical conditions like glycogen storage diseases (GSDs), where the body cannot properly form or break down glycogen, leading to a range of symptoms, including muscle weakness and low blood sugar levels.

In summary, glycogen is an essential fuel reserve in the body, enabling quick access to energy when needed, and its regulation is vital for maintaining normal blood glucose levels and energy homeostasis.

Anthocyanin is a type of water-soluble pigment that belongs to the flavonoid group of compounds. It is responsible for the red, purple, and blue colors found in many fruits, vegetables, and flowers.
