What Serves As The Body’s Chief Storage Site For Lipids??
The main role or function of white adipose tissue is to collect store and then release lipids. However because of the properties of the lipids being stored the adipose tissue also acts as a protective cushion (resists knocks) and also as a layer of insulation against excessive heat loss.
What helps determine a person’s susceptibility to obesity?

What does the hormone ghrelin control?
Ghrelin is a hormone that is produced and released mainly by the stomach with small amounts also released by the small intestine pancreas and brain. Ghrelin has numerous functions. It is termed the ‘hunger hormone’ because it stimulates appetite increases food intake and promotes fat storage.
Where is ghrelin hormone produced?
Ghrelin is a hormone produced by endocrine cells in the stomach. Ghrelin stimulates the secretion of growth hormone by the anterior pituitary. This effect is mediated by hypothalamic growth-hormone secretagogue receptors.
What does the hormone ghrelin do?
Ghrelin is a multifaceted gut hormone which activates its receptor growth hormone secretagogue receptor (GHS-R). Ghrelin’s hallmark functions are its stimulatory effects on food intake fat deposition and growth hormone release. Ghrelin is famously known as the “hunger hormone”.
Where are fats stored in the body?
Subcutaneous fat makes up most of our bodily fat and is found under the skin. This is the body’s method of storing energy for later use. Visceral fat is found in the abdomen amongst the major organs.
What factors affect body fat distribution?
The known major environmental factors that affect body fat distribution include alcohol intake (1) cigarette smoking (2) and the timing of onset of childhood obesity (3). In addition strong genetic factors seem to play a role in regional fat gain and loss (4 5).
Where is protein stored in the body?

How do adipocytes store fat?
What gets stored in fat cells?
Adipose (fat) cells are specialized for the storage of energy in the form of triglycerides but research in the last few decades has shown that fat cells also play a critical role in sensing and responding to changes in systemic energy balance.
What does the fat reservoir do in a fat cell?
Its main role is to store energy in the form of fat although it also cushions and insulates the body. Obesity in animals including humans is not dependent on the amount of body weight but on the amount of body fat – specifically adipose tissue.
