Contrary to popular belief, haemoglobin is not a blood protein, as it is carried within red blood cells, rather than in the blood serum. Serum albumin accounts for 55% of blood proteins, [1] is a major contributor to maintaining the oncotic pressure of plasma and assists, as a carrier, in the transport of lipids and steroid hormones.

The average 70 kg (150 lb) adult human body contains approximately 7 × 10 27 atoms and contains at least detectable traces of 60 chemical elements. [5] About 29 of these elements are thought to play an active positive role in life and health in humans. [6]
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but which contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. [1] It is the intravascular part of extracellular fluid (all body fluid outside cells).
Blood-proteins, also termed plasma proteins, are proteins present in blood plasma. They serve many different functions, including transport of lipids, hormones, vitamins and minerals in activity and functioning of the immune system. Other blood proteins act as enzymes, complement components, protease inhibitors or kinin precursors.
Researchers have identified protein signatures in blood tests that can be used to detect or predict up to 67 diseases, using UK Biobank data in a cohort of nearly 42,000 participants.
Arterial blood carries oxygen from inhaled air to all of the cells of the body, and venous blood carries carbon dioxide, a waste product of metabolism by cells, to the lungs to be exhaled. However, one exception includes pulmonary arteries, which contain the most deoxygenated blood in the body, while the pulmonary veins contain oxygenated blood.
Molloy advises people to eat about 0.75 grams of protein per pound of total body mass, or 1.6 grams per kilogram. A 2022 study supports this, finding that 0.7 grams per pound of body weight was ...
