A ball-and-stick molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.
Bovine beta-lactoglobulin protein, 3D structure. Major whey protein, present in cow milk. Important food allergen.
Rapamycin, also known as sirolimus is a macrolide compound that has immunosuppressant functions and prevents transplant rejection through the inhibition of  the protein complex mTORC1.
Streptococcus pneumoniae is responsible for causing severe acute bacterial infections like pneumonia, sepsis, and meningitis. Distinguishing it from other alpha-hemolytic streptococci is achievable by assessing its susceptibility to optochin (shown in the pic), as indicated in the accompanying image. Notably, the pneumococcal polysaccharide capsule plays a crucial role in evading phagocytosis, contributing to its pathogenicity.
