The growth hormone deals with fat catabolism by the cells. The growth hormone is secreted by the anterior pituitary in the endocrine system.
Cytokines such as interferrons and interleukins are secreted by the T cell in response to antigen. These chemicals are also secreted by B cells, dendrictic cells and natural killer cells. These chemicals are signalling agents that modulate (or properly control) the immune response
Proteases are secreted in their inactive forms so as to prevent self-digestion and the destruction of the body's own cells. This is because all cells have proteins and hence are susceptible to the catabolic effects of proteases. However, amylase is not secreted in an inactive form as we do not store starch in our cells, but rather, we store carbohydrates in the form of glycogen. Therefore amylase poses no risk to our cells. Lipase-secreting cells also do not contain lipids and therefore lipase poses no threat to the body's own cells.
Yes, insulin is secreted by the pancreas. This secretion is part of the endocrine function of the pancreas.

Keratin is a tough, waterproofing protein. Keratin is secreted by the cells of the epidermis (the outermost layer of skin).
A gonadotrophin is any of a group of protein hormones secreted by gonadotrope cells of the pituitary gland of vertebrates.
A gonadotrophin is any of a group of protein hormones secreted by gonadotrope cells of the pituitary gland of vertebrates.

Proteins do most of the work in cells. Proteins are required for the structure, function, and regulation of the bodyâ??s tissues and organs.
Leptin is a protein that is secreted from adipose (fat) cells. It acts on receptors in the Central Nervous System and other sites to induce energy expenditure and inhibit food intake (Margetic et al. 2002).
Cortisol is a steroid hormone made by the adrenal gland. This helps keep the regulation of blood pressure and cardiovascular function.
Leptin is a hormone of a protein nature , secreted from fat cells and received by the hypothalamus , linked with a number of functions in the body as being an inhibitor of appetite ( antagonized by other feeding stimulants ) , giving a feeling of fullness ( that's why it's used now in some diets for weight loss , dangerous and can cause angiogenesis ) , induces surfactant expression which is a very important substance secreted by cells in the lungs for respiration , very important for fertility in both sexes and essential for growing up ( from the reproductive point of view ) .NB : Leptin reduces appetite , however , its circulating level is high in obese individuals because they show resistance to leptin effects .
it is secreted by stomach glands as an inactive proenzyme, pepsinogen, which is converted to pepsin by the cleavage of acid-labile linkages in the acidic (low pH) environment of the stomach.
Pretins that are secreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane.
